FASTENING DEVICE.

United States of America, residing at De troit, in the county of Wayne and State of Michigan, and Chicago, county of Cook, Illinois, respectively, have invented certain new and useful Improvements in Fastening Devices, of which the following is a specification, reference being bad therein to the accompanying drawings.

Glaziers when mounting plate glass in window frames, show cases and other structures are instructed to leave a defined space between confronting edges of glass plates and not tighten the fastening means of the glass plate too much, but instead of obeying such instructions it will be found that glass plates are mounted so that they arebroken, either due to expansion or too great a pres sure on the plate by the fastening means thereof. Some times a glazier will use a wrench, pair of pliers or other tools to operate the fastening means of the glass plate and when such spring pressure is brought to bear on the edges of the plate the glass is invariably blemished, cracked, chipped or sometimes the entire plate broken. WVhen not leaving sufficient space at the confronting edges of two plates for expansion of either, one or both of the plates may be injured, as mentioned above, so to prevent such negligence on the part of the glazier we have devised plate glass holding means which will assure the'proper amount of space between the confronting edges of the glass plates and at the same time prevent the glazier from bringing excessive pressure to hear when clamping or mounting the plates inthe frame between the clamping rails.

Our invention further aims to provide 2 a plate glass fastening device which cannot be installed except by providing the defined space between the confronting edges of the glass plates, and after the fastening device has been installed it is practically impossible to adjust the fastening device except with the fingers and consequently too great a pressure, as by leverage,cannot be brought to bear on the fasten ng device.

Our invention further aims to provlde a glass plate fastener that may be used at the edge of a glass plate whether the same is in alinement with another plate, a at an glass;

angle thereto mat a rail or other support, consequently we do not care to confine our invention to any particular window or show case construction, other than as defined by the appended claims.

Our invention will be hereinafter more fully considered and reference will now be had to the drawings, wherein Figure 1 is a side elevation of a fastening device in connection with the two plates of Fig. 2 is a rear elevation of the same;

Fig. 3 is a horizontal sectionalview of the fastening device;

Fig. 7 is a horizontal sectional view taken on the line VII-VII of Fig. 6;

Fig. 8 is a cross sectional view of a modified form of fastener, and I Fig. 9 is a horizontal sectional view taken on the line IXIX f Fig. 8.

Reference will first be had to Figs. 1, 2 and 3 showing the fastening device as holding the confronting edges oftwo alining glass plates 1 between an inner frame or rail 2 and an outer frame or rail 3. Theinner frame 2 is hollow and more or less ornamental with two inwardly projecting longi- 1' are placed with or without gaskets or cushion members therebetween.

The outer rail or frame 3 is somewhat in the form of a channel bar providing opposed longitudinal guides 5 and a central .tudinal flanges 4; against which glass plates longitudinal raised portion 6 which takes ,7

the form of a head on the outer frame.

Mounted in the guides 5 of the outer frame 8 is a longitudinal plate 7 and contrally of said plate is a tension member or tie rod 8 having a head 9 in the raised portion or bead 6 of the outerframe 8. The plate 7 serves as a large head on the end of the tie rod 8 and permits of said tie rod beingshifted in the outer'yframe to a desired'position. The tie rod 8 is adapted to be inserted between the glass plates 1 and into the inner frame or rail 2 so that the guides 5 of the outer frame will cooperate with the 'fianges 4c of the inner frame in clamping and holding confronting edges of the glass plates 1. A gasket or suitable cushion member may be interposed between the glass plate and the outer frame. Before the tie rod 8 can be inserted between the glass plate 1, 1h 1s necessary that said plates have the confronting edges The tie rod8 has a threaded end 11 extend ing out of the. wall 12 of the inner frame 2 and provided with a knurled nut 13, which is held against the wall 12 by a housing or strap 14; pivoted or otherwise connected, as at 15, to the wall 12. The housing or strap 14; has its side edges cut away, as at 16, so as to expose the periphery of the nut 13 and permit'of the fingers readily grippingthe same to rotate the nut and shift the tie rod 8. The housing or strap l4 prohibits the use ofa wrench, pair of pliers or other tool for rotating the nut, consequently excessivepressure cannot be broughtto bear by the tie rod 8 which would cause the inner and outer rails to crack or otherwise injure the glass tween said frames. 7

As shown in Figs. 1 and 2 the fastening devices can be suitably spaced throughout the inner and outer frames so that the confronting edges of the glass plates will be positively held between said frames.

The principle thusfar involved maybe embodied in corner frames 17 and 18 shaped for engagement with the edges of glass plates 19 placed at an angle relative to each other, andoutside of the frames 17 and" 18 being shaped to engage the glass plates the fastening. device is identical with that previously described.

The fastening device for the edge of a single glass plate 20 is shown in Figs. 5, 6 and 7, the glass plate being engaged by an inner frame or rail 21 and an outer frame or rail 22, both of which may have a desired cross-sectional shape or be more or less ornamental and similar to molding. The-outer frame or rail 22. affords guides 23 for, a plate or head 24? carried by a tie vplate 25 which extends into a journal member 26 fixed in the inner frame21. The tie plate 25 has an opening or slot 27 providing. clearance for a cam or an eccentric 28 on a. stem 29 journaled in the member 26. The upper plates 1 clamped beend of the stem, within the frame 21, has a knurled nut 30 with a portion of its periphery, protruding from a slot 31 in the frame 21, so that the nut may be gripped with, the fingers to rotate the stem 29 and turn the cam or eccentric-2S in the opening or slot 27. The turning of the cam or eccentric 28 shifts the plate 25 and moves the outer frame or rail 22 relative to the glass plate 20, whereby it is possible to clamp the glass plate between theinner and outer frames. This is accomplished without any danger of excessive pressure being brought to bear upon the edge of the glass plate by either of the frames or rails. f

A. modification of the fastener is shown in Figs. 8 and 9, wherein the journal member 26 has stamped out portions 32 providing a guide for the end of the tie plate 25, which is provided with an angular flange 33 engaging the journal member 26. In the j ournal member is a screw 3 l'having a knurled nut 35 disposed similar to the nut 30 and on the screw 84 is a wedge nut 36 non-rotatably held by the tie plate 25 and adapted to be raised and lowered against the flange 33 of said tie plate to move the outer frame 22 relative to the inner frame '21. The tie plate 25 hasan opening providing clearance forthe wedge nut 36, as bestshown in Fig. 9 and this form OfffiSllGIlGl,- ZIS well as that shown in Figs. 5,6 and 7 permits'of lateral pressure being brought to bear on the tie plate to properly clamp the edge of the glass plate 29 between said frames.

VVhatwe claim is i 1. A glass plate fastener comprisinginner and outer frames, tension means engaging one of the frames and extending to the other for moving oneframe with relation to the other, rotatable fastening means engaging the tension means and the other frame and a housing partially enclosing the rotatable fastening means to permit its rotation by'the fingers but to prevent effective engagement therewith of a grasping tool.

2. In a glass. platefastener, frames, and adjustable means for clamping said. frames against the glass plate said adjustable means having a portion thereof enclosed and a portion exposed whereby movement of the ad'- justable means may be accomplished by grasping; it with the fingers, but the enclosed portion being inaccessible to agrasping tool so as to prevent excessive adjustment. i

3. The combination with a glass plate, of a frame, clamping means for said glass plate on said frame and means for adjusting said clamping means having a portion enclosed and a portion accessible to the fingers of "the operator whereby adjustment of theclampin means may be made. by the fingers while the presence of the enclosure renders theuse of a grasping tool difficult. V r

4-. The combination with glass plates, of inner and outer frames engaging the adand extending between the edges of the plates and the other end adapted to I'GCGIVG means whereby it is secured to the other frame and a spacing member secured upon the tension member at a distance from its point of attachment to their first named frame greater than the thickness of the glass plates, whereby in assembling the frames upon the plates, sufficient space must exist between the adjacent edges of the plates to permit the passage of the spacing means, but when the frame lies in contact' with the plates, the spacing mem her lies at one side of the plane of the plates.

5. The combination with glass plates having the edges thereof spaced apart, of means insertable between the edges of the plates to hold the plates in clamped position, said means having thereon a spacing member of such dimensions that when the clamping means is inserted, the plates must be at least a predetermined distance apart to permit the passage of thespacing member, and the said spacing memberbemg so located upon the clamping means that when the parts are assembled the spacing member does not lie in the plane of either plate.

6. The combination with glass plates having edges thereof spaced apart, of an outer frame, a tiered having one end rigidly secured to the outer frame and having thereon a spacing member spaced from the outer frame a distance greater than the thickness of the glass plates, and an inner frame through whichthe tie rod extends, and means engaging the tie rod and the inner frame,

adapted to exert longitudinal tension upon the tie rod to clamp the frames in position on the glass plates.

In testimony whereof we affix our signatures in presence of two witnesses.
